Abstract
A number of racks make up a stack. An upper rack includes releasable catches received into orifices in the next lower rack to releasably attach the two racks to one another. A loader and receptacle cooperate with one another to release the bottommost rack from the stack and deposit it into the receptacle where pipette cones held therein are accessible for use. The bottom rack is placed into the loader where it is held by catches engaging ribs of the rack. The stack of racks with the loader attached is placed onto the receptacle. The stack of racks is pressed downwardly. The downward movement releases the bottom rack from the loader. At the same time, studs projecting up from the bottom of the receptacle engage catches of the second-from-the-bottom rack and free the bottom rack. The bottom rack now rests freely in the receptacle.
